[Elecraft] Cleaning a K3

[Gary K9GS]

Josh is exactly correct, DI is the standard.   Surfactants are sometimes added to increase the wetting on the board and reduce the surface tension.
I think that distilled water, under the right conditions is actually corrosive.

DI water is the standard, usually in a closed loop system. Most process 
now use water soluble flux. If not, sometimes a wash with addition of 
soap and/or solvent is done prior to the DI water rinsing.
